ISY S-Reduce

Product detailed description

AB Vickers ISY S-Reduce™ is an inactivated specific yeast autolysate rich in biologically-bound copper that can remove suflur off-flavors from beer including hydrogen sulfide (H2S), dimethyl sulfide (DMS) and mercaptans. The sulfur compounds precipitate with the copper and are removed with the yeast leaving the beer tasting fresh and clean.

Principle

AB Vickers ISY S-Reduce™ is rich in copper that is immobilized to the yeast cell fraction. When applied to the beer, the copper reacts with sulfur compounds in the beer to form insoluble precipitates. The sulfur is then removed along with the biologically bound copper when the beer is transferred off the yeast or clarified by fining or filtration. AB Vickers ISY S-Reduce™ is gluten-free

Benefits

Efficient reduction or removal of hydrogen sulfide (H2S) from beer. Potential reduction of other sulfur compounds including dimethyl sulfide (DMS) and mercaptans.
Avoid extended maturation for the purpose of reducing sulfur off-flavors.

Dosage

10-30g/hL
Dissolve AB Vickers ISY S-Reduce™ in about 10x its weight of sterile, deaerated water. Stir well and then mix thoroughly with the beer
